kernel.h: drop hex.h and update all hex.h users

2026-01-21T03:44:19+00:00

Remove from and update all users/callers of hex.h interfaces to directly #include as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of in the entire source tree have been updated if needed (if not already #included).

platform/x86: wmi: Do not instantiate older WMI drivers multiple times

2024-03-12T10:47:35+00:00

Many older WMI drivers cannot be instantiated multiple times for two reasons: - they are using the legacy GUID-based WMI API - they are singletons (with global state) Prevent such WMI drivers from binding to WMI devices with a duplicated GUID, as this would mean that the WMI driver will be instantiated at least two times (one for the original GUID and one for the duplicated GUID). WMI drivers which can be instantiated multiple times can signal this by setting a flag inside struct wmi_driver. Tested on a ASUS Prime B650-Plus.

platform/x86: intel-wmi-sbl-fw-update: Fix function name in error message

2024-01-22T10:37:28+00:00

Since when the driver was converted to use the bus-based WMI interface, the old GUID-based WMI functions are not used anymore. Update the error message to avoid confusing users. Compile-tested only.

Currently, the driver still uses the legacy GUID-based interface to invoke WMI methods. Use the modern bus-based interface instead. Tested on a Lenovo E51-80.
